‘robocall strike force’ proposal could stop caller id spoofing – slashdot database image _ data recovery

This summer the FCC convened a “Robocall Task Force” to help consumers fight unwanted automated telemarketers, and Wednesday the coalition finally delivered a report recommending a “Do Not Originate” list so carriers could spot spoofed numbers which should be blocked.

A trial of the “DNO” list that’s been running for the last few weeks on some IRS numbers has resulted in a 90 percent drop in the volume of IRS scam calls, officials from AT&T, which leads the strike force, said during the FCC meeting Wednesday. Database management jobs Database acid The carriers on the strike force, which include Sprint, Verizon, and many others, plan to continue testing the DNO list in the coming months, with the intent to fully implement it some time next year…

The strike force members also are working on a system to classify calls into categories, such as political or charity, as a way to give consumers more information before they answer calls from unknown numbers.

Early next year they’re planning larger tests — and the strike force has also created a new site describing how to block and report robocalls.

And for some reason, a lot of them think that a robocall with their wife on it actually makes a difference. Data recovery ubuntu Database analyst salary And if those robocalls actually make a difference, well my opinion of the American people cannot get any lower.

You explanation is perfectly valid for why a business might assert a particular CID that is valid within the company, but not what carriers allow people to assert any CID not registered to that individual or company.

The only way to solve this problem is to make the carriers accountable for allowing such behavior.

Because when the system was put in place no one foresaw VOIP and the extremely low barrier to entry for doing this.

I’m not the the OP, oh ye of poor reading skills, so my first question was for a list of compelling reasons to keep a clearly broken design that only benefits telemarketers and some businesses and presents constant problems for every other user of the system.

We here are the sort of people who design systems, so we need to design a system that doesn’t facilitate arbitrary ID spoofing. Database implementation Database business rules Your “look up how VOIP works” comment makes me think that you’re not a designer of systems, but a lever-pulling operator monk

If I were to design a protocol of this kind, one of the first measures I would take, in the protocol itself if relevant and in any implementation, would be to check that peer-provided source addresses match the routing system, making spoofing impossible. Raid 1 data recovery software Database blob I cannot fathom that the people who designed this particular protocol did not do the same from the beginning, and even more so that they did not fix it since then.

The PBX was fed with trunk lines which actually phone numbers, usually unrelated to the called number. Seagate data recovery Database backup and recovery When an inbound call was made to 555-1000, telco switched that call at the CO to one of the trunk lines. Database report Database building Outbound calls worked basically in reverse, the call went to the PBX which chose an open trunk and completed the call.

Direct Inward Dial (DID) involved buying a block of numbers which had no physical line associated with them and these were programmed to be switched to a trunk at telco with signaling that passed the called party number to the PBX so it could complete the call to the internal extension.

This system had to be adapted to caller ID. Data recovery specialist Database backend Early outbound calls often showed the trunk’s phone number, but IIRC you could get telco to basically rewrite those calls to a customer specific number, usually the main number, if your switch lacked the software or signalling to pass the calling extension out.

PBX software eventually got the ability to pass an extension’s DID to telco, so caller ID passed to the called party would see the number the call came from, even though it may have passed over an analog trunk with a completely different assigned phone number.

Basically, caller ID has, for anything other than single POTS or cell lines where telco handled all the switching, been a kludge on a system that wasn’t built for caller ID, and spoofing was a necessary feature.

The problem all along has been lazy and/or greedy telcos who never bothered to implement sanity testing on spoofed calling party info and just accepted all of it rather than build in checks that the calling party info actually represented numbers assigned to the calling party.

And I’m sure much of it was made worse by call centers, for whom number spoofing was a business feature — doing business for a company who WANTED call center calls to come up as their numbers. Data recovery iphone 6 Database b tree And VOIP vendors who wanted to use IP networks to route calls and unload them onto POTS at the cheapest point, terminating a call from a DID block leased from telco A using circuits leased from carrier B.

Actually, since digital switching began in the 60’s and 70’s, there have been three fields transmitted with every call (well, a lot more, but these are relevant)

BTN = Bill To Number — this is the number that the call is billed to. Database building Yale b database This is actually validated by the connecting carrier, and still is today.

This biggest problem is that we started getting a lot of smaller CLECs that didn’t understand the technology well enough and started giving everybody closer access to the PSTN (for example, by not watching the CPN they were sending). Database languages Database constraints The problem was exacerbated when VoIP became a thing and CLECs started allowing anybody access to the PSTN with no restrictions and no regard to their physical location.
